Magic: The Gathering head designer Mark Rosewater has caused a stir with his claim that fully half of MTG sets going forward would be Universes Beyond crossovers like Spider-Man or Teenage Mutant Ninja Turtles.
As you might expect from a community that has… mixed feelings about Universes Beyond to begin with (there's been a lot of debate about their increased frequency and how they don't always 'fit' with the high fantasy style of MTG), that's gone down about as well as you'd expect. It's also stirred up an interesting discussion amongst fans of the best card games. How much Magic: The Gathering is too much?
